Masdar City, the world's first carbon neutral city that's banned cars and skyscrapers from its streets, gives us a glimpse of what other parts of the world might look like in the future. Located in Abu Dhabi and financed by the city's ruler Sheikh Khalifa bin Zayed Al Nahyan (who has pumped between $15bn and $30bn into it already), the city spans six square kilometers and will house around 50,000 people.

The city staged its first open day on the weekend, giving locals and tourists a look at what they could be living in if they choose the Masdar way of life. You can see in the gallery below that they allow Mitsubishi i-MiEV electric cars in Masdar, and have driverless electric pod trains, but apart from that it's two legs all the way.
